"I got several estimates from several providers. The pricing seemed just ok with those other providers but something seemed off. Good Life came in and made sure that I was getting the correct amount of insulation (where the other service providers had under estimated) and helped me to get into a loan through the utility company for the cost of the insulation. Good life is a qualifying contractor for this and it saved me a lot of out of pocket expense. They came in and did what they had to do. They were professional and made sure the work was done well."

"Great Customer Service equals great company. This is the first review I have ever written, but I was so impressed with Good Life Energy Savers that I had no option. Based on other internet reviews I hired Good Life Energy Savers to insulate my attic and exterior walls. Based on only a two-year sample I saved about 20% on my oil costs, but that is not why I am writing this review. This past Friday I called Good Life Energy Savers about an issue I found. I was told they would get back to me on Monday, and they did. They asked if they could come by to see the issues the same day, which they did. They acknowledged the issue and simply said they will take care of it, and they did. On Thursday morning a crew came by to fix it. They did an excellent job and went above and beyond to satisfy me (the customer). Having been in the business world for over 40 years, I know not every job goes perfectly, so good customer service is important. This was excellent customer service. I could not believe the effort they put in to make the job perfect. Thank you, Mike and the team Sincerely, Mark O"

"Everyone was very courteous, on time, and the personalities of the entire team were amazing. Edgar and crew made this project very easy and we are very very very very pleased! AJ kept us updated and was very helpful as well with the project. I will keep them in mind for our next projects and would definitely recommend to our friends and family members. Also Iâ ve already noticed the air quality difference from our new roof and now insulation. Job well done all around"

"I liked that the first questions we were asked was "Have you had a home energy audit done? Did you know you can get a rebate on your insulation project?" Before even knowing the scope of our project, they were looking to help make it more affordable for us."

"Perfect wall LLC service was amazing! They went over the job with me and explained everything and taught me a thing or 2 about insulation. After the job I went to look at the results and it was exactly how he explained it! They use measuring templates you can see the actual depth of the insulation in all parts of the attic which was awesome. The vent out the exterior wall was so perfect I couldn?t even find it unless I really looked. Everything came out perfect they took the time to clean up very well also which my wife was very happy about! 10/10 would use again."

"The consultation went great. Cary came out and spent about an hour measuring and evaluating our basement. He left me with a quote the same day as well as my options. Although a little pricey we decided to go for it. The guys came out a few weeks later to insulate and were here all day. No issues there. However, the basement has not warmed up since and we spent quite a bit of money and were told it would be about 60-65° down there. It only increased by maybe 5° and still isn’t even close to 60/65°. I emailed the guy Cary who came out and was told he’d talk to his guys about it. No response. I had to follow up. Then he said he’d send someone out. Never got a call or anything to schedule it. Again I had to reach out. Weeks later he finally said he’d come out on 3/18/21 at noon. It’s now almost 1pm and he’s still not here. Their service was great when they wanted our money but now that we have paid, it seems we are not longer a priority and they don’t care to come fix whatever the problem may be. Very disappointing. We spent thousands of dollars and our basement still feels very cold!"

Insulation FAQs, answered by experts

You don’t need to staple insulation, as your drywall and studs will hold it into place. But if you already have a staple gun and staples lying around, it can help keep the product in place and avoid any shifting. But, most experts agree it’s an unnecessary step.

If you’re adding a vapor barrier, you will need to staple that in place.

The lifespan of cellulose insulation is 20 to 30 years, on average. That said, it’s important to start checking your insulation after year 10 to check for degradation, mold, mildew, and other potential problems. Every 10 years, you should also confirm your home’s insulation is in line with updated local building codes.

If the temperature outside is around 90 or 100 degrees with the sun beating on your home’s roof, it’s common for the attic temperature to reach 150 degrees or more. This excessive heat shows the importance of having a radiant barrier in place along with insulation. The radiant barrier reflects the heat entering the attic back upward, keeping your home’s temperature more consistent.

There are many reasons one bedroom may be hotter than the rest of the house. The sun will quickly heat a south-facing bedroom with a large window, especially if it lacks quality curtains. If the room has poor insulation, this could let more warm outside air in. Upstairs bedrooms are often hotter than ground-floor rooms because heat rises. Finally, rooms further away from the air conditioning unit may heat up a lot if the system is not properly balanced.

Unfortunately, pipes can freeze when exposed to prolonged freezing temperatures, whether or not you have installed insulation covers. Insulation covers, however, are still an excellent idea as they can reduce the chance of your pipe freezing by keeping the pipes closer to the temperature of the water inside the pipe.
